Many students feel that Elzinga's ECON201 class is a must-take. I disagree. Elzinga is a really great person and a good professor, but if you're interested in pursuing economics, take the class in a smaller setting. The tests are hard to the extent of not really being fair, and the TAs are notoriously horrible. Meet with Elzinga during his office hours, but don't take his class.

A very enjoyable, if not necessarily enlightening class

This is required for COMM and ECON students, but if you have to take it, take it with Elzinga. Even if you don't have to take it, ECON 201 is a great grounding in some general principles that can be very useful to know. He even gives a lecture on the beer market (makes concepts fun to learn about). Be prepared to deal with the bureacracy of big-class testing and grading though.
